Patent DE-3016458-A1 (DE)
Title: Coating thickness of article measured immediately after application - by radiometric thickness method and used to regulate coating apparatus
Inventor: BENZ GERHARD DIPL PHYS DR
IPC: B05B12/12
Filed: 1980-04-29
Abstract: A method of determining and/or controlling the thickness of a coating, such as a lacquer or powder coating, applied to workpieces, for example by spraying or sprinkling, where the thickness is adjusted either by adjusting the coating apparatus or adjusting the speed of travel of the workpiece through the apparatus, is as follows. The thickness of the coating or on a test piece coated simultaneously with it, is measured by a known radiometric thickness measuring method without contact, pref. immediately after the workpiece leaves the coating apparatus. Pref. the workpiece or test piece passes the radiometric coating thickness apparatus in a zone outside a spray cabin surrounding the coating apparatus; the distance between the workpiece and the test apparatus is kept constant, at least during the measuring operation. The method makes possible immediate checking of the coating thickness and therefore almost immediate adjustment of the coating apparatus if a fault or deviation occurs. This is by contrast to the known methods, where the coating thickness is measured by a contacting process after the coating has hardened, and there is therefore a delay of 20-30 minutes before the coating device can be re-adjusted. A typical example of use is in a coating plant for the electrostatic powder coating of refrigerator components.

Title: Pressure relief valve for packing bag - has projections on valve foil to prevent adhesion to sealing cpd.
Inventor: SAUR WALTER
IPC: B65D77/22
Filed: 1980-12-12
Abstract: A pressure relief valve for a packaging container esp. bag package, is in the form of a multilayer label possessing a valve duct bounded by mutually facing foils and filled with a viscous sealing agent. At least one of the surfaces which bounds the valve duct has projections on it. The projections may be produced by roughening the surface, for example by means of a brush, grinding agent, needles by embossing or by corona discharge. The projections may be regular or irregular in their distribution and have a height of 10-20 micron. The foil sheets bounding the duct are pref. of polyethylene terephthalate. With this arrangement, the projections ensure that at least one of the foils is not in contact with the viscous sealing agent and consequently there is no adhesion to this agent. As a result a valve which is very sensitive to slight pressure differences is achieved, and it will react to pressures as low as 10 mbar.

Title: Circuit arrangement for measuring impedance matching by means of a directional coupler
Inventor: KREBS HELMUT
IPC: H03H7/38
Filed: 1981-05-15
Abstract: For tuning antennas, in particular, a circuit arrangement for measuring impedance matching by means of a directional coupler of concentrated components is needed which, even with small mismatches, still supplies a sufficiently high transmitted voltage when fed in through a test transmitter so that a display on the oscilloscope is possible. For this purpose, the directional coupler arranged in a transmission line contains a current transformer with an ohmic voltage divider (R, R), connected to the secondary side, and a load by impedances (Z, Z) in accordance with the characteristic impedance of the transmission line (1, 2). To compensate for the phase displacement of the loaded current transformer (L, w), a single series capacitor (C) is provided between the wire (1) of the transmission line (1, 2) in which the current transformer (L, w) is located and the symmetric tap (compensation point K) of the ohmic voltage divider. In this arrangement, a particular dimensioning of the said components must be maintained. <IMAGE>

Patent DE-3140322-A1 (DE)
Title: Trailer coupling for coupling single-axle trailers, such as caravans and similar towed vehicles, to towing vehicles
Inventor: RICHTER KARL-HEINZ
IPC: B60D1/173
Filed: 1981-10-10
Abstract: In a trailer coupling for coupling single-axle trailers, two trailer struts are provided instead of a shaft, which struts are coupled to the superstructures of towing vehicle and trailer, preferably in a symmetrical arrangement with respect to the transverse centre line of the vehicle. The mutual spacing of the coupling points of the trailer struts on the trailer is greater than that of the coupling points present on the towing vehicle by such a degree that the axes of the trailer struts intersect at a point lying on the transverse centre line of the towing vehicle which preferably coincides with the centre of gravity of the towing vehicle. By means of the arrangement of the trailer struts converging in the direction of the towing vehicle it is possible to place the coupling point on the towing vehicle at an ideal point so that interference forces which act on single-axle trailers and normally adversely affect their road holding remain ineffective and the driving stability of the single-axle trailer is ensured even in extreme driving situations and at high speeds.

Title: Press drive, especially for hydraulically operated coating presses
Inventor: KNAEBEL HORST DIPL ING
IPC: B30B15/16
Filed: 1981-12-15
Abstract: In the invention, a press drive, especially for hydraulically operated coating presses, according to the main patent P 3130931.3, is to be improved to the effect that a reduction, necessary by virtue of the process, of the time required from the start of the advance movement until the prepressing forces reached is achieved by a decrease in the hydraulic fluid needed for the fast stroke and, by means of further embodiments of the invention, a press drive which is easy to maintain and which can be operated at a reduced energy outlay is provided. The object is achieved in that a piston rod (35) of smaller diameter is connected to the existing piston (1) on the side of the differential piston (5) located opposite it, with the result that, in the course of the fast-motion stage, an effective surface of the differential piston (5) loaded with medium pressure is obtained from the difference between the surfaces formed by the piston (1) and by the piston rod (35), and, during the working stroke, the effective surface is formed from the difference between the surfaces generated by the differential piston (5) and the piston rod (35), and a coordination with the pressure level necessary by virtue of the process takes place. In the press drive there is provided, for energy saving, a pump (21) which automatically switches to the feed amount "0" after the maximum pressure in the pressure vessel (24) has been reached. <IMAGE>

Abstract: A shelving system comprises two stands (26B, 26C), whose bars (28, 30) are arranged to correspond to a trapezium in contour, and at least one shelf (60A) which is held between the stands (26B, 26C) and has attachment angles (46B, 46C) on its end sides (64, 66) adjacent to the stands (26B, 26C). Said attachment angles have a horizontal limb (48C) and a vertical limb (54C) which engages at both ends with tongues (56C) in vertical grooves (34) provided on the insides of the bars (28, 30), where the tongues (56C) rest on bolts (42). In order to allow easy mounting and demounting of the shelf (60A), the two limbs (48C, 54C) of the attachment angles (46B, 46C) are hinged to one another in a foldable manner, and the horizontal limbs (48C) are held on the shelf (60A) near to the bars (30) lying further apart so as to be pivotable about an axis formed by a bolt (112) perpendicular to the shelf (60). In the mounted position, pivoting of the horizontal limb (48C) is avoided by means of a further bolt (114). The openings in the horizontal limb (48C) through which the bolts (112, 114) penetrate are constructed as elongate holes. The shelf (60A) has recesses (146) near to the bars (30) lying further apart in order not to strike against these bars (30) during a folding movement which is required for mounting. <IMAGE>

Title: Lottery-number drawing unit
Inventor: OCHSENKUEHN ERHARD
IPC: G07C15/00
Filed: 1982-02-16
Abstract: What is described is a handy lottery-number drawing unit having a flat housing which is subdivided into two spaces of different size by a slide channel in which two slides under spring pressure are located. In the larger space is a supply of balls which are marked with the various lottery numbers and which are mixed thoroughly by shaking the housing. When one slide is pressed in, it passes successively with a transverse bore to an orifice connecting the slide channel to the ball supply space, so that one of the balls can slip into the slide bore. When the slide is pressed in further, the ball falls through an opposite orifice in the slide-channel wall into the other space. For a six-row of lottery numbers, six balls are thus transferred into the second space. By overturning the housing and pressing the other slide, its transverse bore arrives at two mutually aligned orifices in the slide-channel walls, so that the balls can be brought back into the supply space.
